Description

Air-defense beating assembly, air-defense beating device and nail gun Technical Field The utility model relates to the technical field of nail guns, in particular to an idle-shooting prevention assembly, an idle-shooting prevention device and a nail gun. Background At present, in order to prevent the nail from being used up, an operator cannot find the nail in time, and then the firing pin is possibly excited, so that the operator and surrounding personnel are injured. In order to avoid the problem that the nail gun is empty to be beaten, in the prior art, an idle-beating prevention assembly is assembled on the nail gun, and the nail gun can be prevented from being shot when the nail gun is used up soon, so that the problem caused by idle beating is avoided. In the prior art, an idle-firing prevention assembly of a single-shot nail gun (hereinafter referred to as a nail gun) generally limits a bent rod part of the nail gun, specifically, the bent rod part is a safety of the nail gun, and when the bent rod part is not compressed, a trigger is not activated, so that a safety effect of limiting firing is realized. The safety is relieved, one end of the curved bar component is attached to the working surface, the curved bar component is pushed to slide along the gun head, the trigger safety is relieved, the corresponding push block part is arranged on the push pin block of the cartridge clip, the limiting block is arranged on the curved bar component, when the number of gun pins in the cartridge clip is small, the push pin block can drive the push block part to synchronously move to the push block part to be contacted with the air defense assembly, and the air defense pin in the air defense assembly is pushed to move upwards to the position between the limiting block and the gun body, so that the sliding of the curved bar component is prevented, and the air defense effect is realized. However, because the nail gun may need to be replaced with nails of different specifications and nails of the same specification may have larger arrangement gaps in the use process, the idle-fire-preventing assembly cannot be activated in time, and in particular, referring to fig. 1, when the idle-fire-preventing assembly is activated due to different sizes or arrangement gaps of the nails, but the residual quantity of the nails in the cartridge clip still does not reach the position where the nail pushing block can push the idle-fire-preventing assembly to move to the position between the limiting block and the gun body, the idle-fire-preventing assembly cannot be activated, but in the process of pushing the curved rod component to release the safety, the nail pushing block is supposed to push the nails into the nail shooting channel, but at the moment, the idle-fire-preventing assembly is not pushed by the limiting block to continue to move upwards, and correspondingly, the pushing block part of the nail pushing block is limited by the idle-fire-preventing assembly, so that the situation that the nail pushing block cannot normally feed nails occurs. When the nail pushing block cannot normally complete the complete nail feeding action, the idle-striking prevention assembly is invalid, even if the nail pushing block only completes partial nail feeding, the striking can also cause the firing pin to strike the top cap of part of the gun nail, so that the gun nail is obliquely driven into the wall surface of the nail shooting channel, and the gun head is damaged. Disclosure of utility model In order to overcome at least one of the above-mentioned drawbacks of the prior art, the present utility model provides an idle driving prevention assembly, an idle driving prevention device and a nail gun, which can solve the problem of failure of the idle driving prevention assembly caused by the problem of gun make a detailed inquiry about. The utility model adopts the technical proposal for solving the problems that: An air defense assembly for a nail gun, comprising: A mounting carrier having a mounting hole; the anti-idle-attack pin is movably arranged in the mounting hole through a first elastic piece and comprises an abutting end and a switching end, and the switching end of the anti-idle-attack pin is connected with the abutting piece in a sliding manner; And a second elastic piece is arranged between the idle-strike prevention pin and the abutting piece and is used for pushing the abutting piece to reset. Further, the middle part of the idle-run-preventing pin is provided with a limiting part, one side of the mounting hole, which is close to the abutting end, is provided with a first limiting part, and the first elastic part is arranged between the limiting part and the first limiting part. Further, the limiting piece is a limiting sleeve, the limiting sleeve is sleeved on the idle-strike preventing pin, a synchronous motion structure is arranged between the limiting sleeve and the idle-strike preventing pin, a second limiting portion is
